LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 349.284, dated September 14, 1886.

Application filed February 8. 1886.

To all whom it may concern,.-

Be it known that I, CHARLES G. PETZOLD, of Lawrence, county of Essex, and State of Massachusetts, have invented an Improvement in Loom-Shuttles, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention has for its object to improve shuttles in such manner as to insure a irm retention of the bobbin on the spindle and enable checked or `split bobbins to be employed, my present invention being an improvement on the-shuttle described in my application Serial No. 120,954, filed February 16, 1884.

ln my invention the spindle is provided at its outer end with a head of a diameter suf- 4 cient to act as a race for the yarn and keep it from Contact with the end of the bobbin, and 2o at its other end the said spindle is provided with two notches to engage two pins of the shuttle-body, the said notches being -at opposite sides ot' the longitudinal center ot' the spindle and at opposite sides of the pivot of the spin- 2 5 dle-receiver, the said spindle at its inner end being slabbed off to form an aligning surface, which, Vco-operating with the pivot ot' the said receiver or with the receiver itself, insures the alignment of the holding-notches of the spindle 3o with the pins to enter the said notches when the spindle is turned into the shuttle-body in working position, the receiver being notched between its free end and its pivot to expose the spindle at one of its transverse notches.

My invention consists, essentially, of a shuttle-body having two pins or stops and a pivoted notched or open spindle-receiver, combined with a spindle having at one end an enlarged head or disk, the opposite end of the spindle being provided with an aligning surface and with two notches at its opposite sides to engage the said pins or stops and securely retain the spindle in place, substantially as will be described.

Figine 1 is alongitudinal section of a shuttle embodying my invention, the spindle and bobbin being in working position. Fig. 2 is a like section with the spindle and bobbin turned partially out of the shuttle-body. Fig. 3 shows 'the pivot b.

Serial No, 191,263. (No model.)

the spindle-receiver by itself, and Fig. 4 a 95o cross-section of the spindle at its inner end.

' The shuttle-body a is and may be of usual shape and material. The spindle-receiver b consists of a metal block mounted looselyon The receiver b at one end has a 5 5 shoulder, 2, and a sleeve, 3. The receiver, bored from end to end for the reception of the headed spindle c, is notched or cut away at its under side, as at 5, the said notch being deep enough to intersect the spindle-receiving bore 6o and expose the notch 7 at the lower side of the spindle, so as to enable it to be entered by the pin or stop d, fixed in the shuttle-body at one side of the pivot b. The receiver has a shoulder, 8, to meet the pin or stop d and arrest the outward movement of the receiver, the latter also having a shoulder, 10, and adjacent iiat surface for the cooperation with it of the spring 12, made adjustable by the screw 13, the spring serving to keep the spindle-receiver in the 7C shuttle-body, as in Fig. 1. Just beyond the inner end of the receiver the shuttle-body isl provided with a second pin or stop, d', which is embraced by the notch e at the upper side of the spindle and at the rear of the pivot b, the spindle c, when turned into the shuttlebody, engaging by its notched parts 7 and e both the pins d and d, as in Fig. 1,which pins so hold the spindle that it is impossible to withdraw the same from the receiver until after 8c the receiver is partially turned out of the shuttlc-body, as in Fig. 2. If that part of the spindle within the receiver was round it would be necessary for the operator to use very considerable care when inserting the spindle into the 8 5 receiver to see that the two notches 7 and e .were in correct position to co-operate with and der the pivot b and through the receiver the slabbed part of the spindle must be in a eertain denite position, and so whenever the inner end of the spindle passes the pivot b and the shoulder 15 meets the said pivot, the two notches 7 and e will be in alignment with. the two pins or stops d d. The operator has only to push the spindle into the receiver and turn it in one or the other direction until it nds its way into the space under and beyond the pivot b', which is quickly done and by the sense of feeling'. The spindle at its outer end has a button-like heathf, which overlaps the delivery end of the bobbin, keeping the bobbin on the spindle and also guarding its delivery end, so that checks or splits in the end of the bobbin cannot serve to eateh or detain. the yarn. rlhe spindle has upon it two bearings, 16 17, which forni bearings i'or the bobbin h, which may be of any usual construction. The lower end ofthe bobbin is shown as resting against the shoulder 2 and surrounding the sleeve 3. Vith a receiver and spindle such as shown bobbins of dierent length may be used on the spindle.

I do not broadly claim a spindle with a button or head upon its outer end; nor do l herein claim, broadly, a spindle having an aligning` surface and a single notch, as such features forni the subject-matter of anotherapplication, Serial No. 120,954, filed February 16, 1884..

I claim- The shuttle-body and pins l fl therein, the spring-held spindle-receiver pivoted in said shuttle-body between its said pins and havingr the notch 5 on its lower side, combined with the headed spindle having the notches e and 7 and an aligningF surface, substantially as shown and described.

In testimony whereoll have signed my name to this specification in the presence of two subscribing witnesses.

CHARLES G. PETZOLD.
